RE: OMGraphicsList.findClosest()

   Thanks, I figured it wouldn't be too bad, but wanted to make sure I
wasn't duplicating the second thing I'd missed.

   Now for the REALLY tricky part :) I have a Layer which is basically a
view to a data model. On my map, I have 3 instances of this layer, all
looking at different types of the same data.

   Somehow, I want to compile the results from these clicks into a single
selection dialog, which will cover hits from all three layers. At the
moment, I'm not sure this is even possible. I've got some workaround ideas,
but most of them aren't reliable and the ones that are aren't good interface
design.

   Anyone ever worked with pulling click results from multiple layers into a
single action? Any ideas on how this might go? At the moment my best
option is a static list as part of the class, which gets populated as the
event passes through each layer, until the last one actually displays the
results. Worry with this is layer visibility - events don't get passed to
invisible layers, correct? So at that point figuring out how to know when
I'm done gets tricky...

   Any help appreciated.
